I'm not sure. I tried to collect what was already (inconsistently)
there. One aim is to be able to correct such mistakes :-)
I don't know which Linux emulation NetBSD has on x86_64 at all.

Sorry, I should have been more clear. The current tree has a lot of
scattered ONLY_FOR_PLATFORMs over the tree for Linux emulation, often
consisting of Linux, NetBSD and FreeBSD, sometimes only NetBSD. This is
clearly suboptimal, since it adds unnecessary maintainance overhead
(adding Linux emulation support for another OS like DragonFly) and is
often incorrect.
The patch tries to uniformly handle this by keeping the platform masks
in one of three forms:
(a) For applications, include emulators/suse_linux/Makefile.application
and specify ONLY_FOR_PLATFORM as architecture list (*-*-i386).
(b) For Linux packages the dependencies have to be rechecked, sometimes
it is done based on OPSYS (now replaced with USE_NATIVE_LINUX),
sometimes not.
(c) For the emulators/suse* packages, keep the masks in Makefile.common.
